Otago motorists should expect continued delays on State Highway 88 over the next three days

Contractors are investigating the damage from last week's downpour, and NZTA says it'll mean up to 30 minute delays between 9am and 4pm.

Scaling works will be under way the Parry Street rockfall site, and investigations at the Burkes slip.

State Highway 87 is expected to re-open this afternoon with a temporary road surface.
